About NiSi Optics

NiSi is a globally recognized manufacturer of premium photographic and cinematographic optical accessories. Founded in 2005 and headquartered in Zhuhai, China, NiSi has grown from a research-focused startup into one of the most trusted names in the filter industry — trusted by landscape photographers, videographers, and cinema professionals around the world.

A Foundation Built on Optical Innovation

What sets NiSi apart from competitors is a relentless focus on material quality and proprietary technology. The brand uses an exclusive grade of lens-quality optical glass in its filters — a standard typically reserved for the finest camera lenses from companies like Nikon, Canon, and Zeiss. NiSi designs and produces its products entirely in-house, controlling every step from glass selection to final coating, which means consistent quality with no compromise.

Central to NiSi's reputation is its patented Nano-Coating® technology, which makes filter glass water- and oil-repellent for easy cleaning and maximum sharpness in any shooting condition. The brand also applies proprietary anti-infrared (IR) light treatment to its ND filters, blocking the infrared pollution that causes the unwanted magenta color casts commonly seen with lower-quality alternatives.

A Complete Ecosystem of Filter Systems

NiSi has developed a comprehensive range of filter systems to suit virtually every camera and lens combination. The lineup spans square filter systems in 75mm, 100mm, 150mm, and 180mm sizes, as well as circular filters, and the innovative JetMag Pro Magnetic System — a fast-attach, locking magnetic filter design engineered for photographers who need to swap filters quickly in the field. The JetMag Pro's ultra-slim profile supports stacking two filters on lenses as wide as 15mm without vignetting, making it an exceptional tool for wide-angle and landscape work.

Beyond camera filters, NiSi has extended its expertise into the cinema world with dedicated cinema filter lines — including Neutral Density, Graduated ND, Polarizers, and specialty optical effects filters — as well as full-frame cinema prime lenses under the Athena and Aureus series. The brand also produces close-up lens kits, macro focusing rails, filter pouches, and other photographic accessories that round out a complete creative kit.

NiSi collaborates directly with professional photographers and filmmakers to refine its products through real-world feedback, and the brand holds more than 20 international patents in photography and cinema technology. With dedicated distribution teams across the USA, UK, Europe, Australia, and Asia, NiSi ensures photographers everywhere have access to local support and warranty coverage. Whether you are a seasoned professional on a commercial shoot or an enthusiast chasing the perfect golden hour landscape, NiSi's filter systems offer the tools to translate your creative vision into a finished image.
